I just don't get it! Help me?

Your situation is a tough one. But first let me make it clear that the guy likes you alot! And obviously it wasnt a mistake to text that to you. But you keep dissapointing him honey. First you didnt say ''i love you'' back and then when he texted u that he missed u, your reply was "huh". If i was him i would be thinking that you didnt realy like me right now. So text him and let him know that you do like him and miss him and would like to try dating again
